Answer for BIR CoW 26 Feb 2023
Subependymal Giant Cell Astrocytoma
Findings
Large well defined hyperdense lesion of size noted arising in the left foramen of monro with ventricular extension causing obstruction leading to the dilatation of bilateral lateral ventricles. calcified subependymal nodules seen
Discussion
Subependymal giant cell astrocytoma - benign slow growing tumour Age – <2o yrs Site- In the lateral ventricle near foramen of monro Associated – Tuberous sclerosis complex Calcified subependymal nodules ,cortical tubers present in Tuberous sclerosis complex DD SEN –Stable lesion , located anywhere around the ventricular wall, especially along the caudothalamic groove. subependymoma - tumor of middle-aged and elderly patients central neurocytoma -"bubbly" tumor arises in the lateral ventricle body Low-grade diffusely infiltrating astrocytoma - arise in the septi pellucidi or fornices, but these tumors typically neither calcify nor enhance.
